🤓 This is excellent information, and well worth the read… I have found in my work experience that the more surgeries my patient had, the more nervous system dysregulation they had.
The information below is also something else to add to a woman’s hyper vigilance.
This topic came up in one of my weekly classes a couple of weeks ago.. so I asked ChatGPT about it..
❗️If you are a woman and you’ve had a surgery or two… Please be aware of the fact that this information can be quite shocking!
❗️Regarding pelvic exams performed on women under anesthesia without their conscious verbal consent prior to surgery…
Per ChatGPT …
❗️Yes—there have been documented reports and studies describing this exact situation. It’s not just anecdotal; it has been a well-documented ethical controversy in medicine.
What has been reported
For decades, some medical students were taught pelvic (gynecological) exams by practicing on patients who were under anesthesia during surgery, sometimes without the patient’s explicit knowledge or consent.
These exams were typically done during gynecologic procedures, but the key issue is that the exam could be performed for training purposes rather than direct medical necessity.
Reports describe situations where multiple students performed exams on the same unconscious patient as part of training.
Evidence from studies
A 2003 study found about 90% of medical students surveyed had performed pelvic exams on anesthetized patients during training.
A 2022 multi-school study found:
84% of students had performed such exams
67% said they rarely or never saw explicit consent obtained
Patient awareness and consent
Some institutions historically argued that patients gave “implicit consent” by agreeing to treatment at teaching hospitals or signing general surgical consent forms.
However, critics—including ethicists and advocacy groups—argue this is not true informed consent, especially for intimate exams.
Legal and policy response
The practice has become increasingly restricted:
Many U.S. states have passed laws requiring explicit consent
As of 2024, U.S. federal guidance requires written consent for pelvic, breast, re**al, and prostate exams done for training purposes, especially under anesthesia.
Hospitals can face penalties if they fail to obtain proper consent.
Bottom line
Yes, this has happened and was historically relatively common in some training settings.
It is now widely recognized as unethical without explicit informed consent, and laws and policies are actively changing to prevent it.
New Research | When the Unconscious Brain Still Listens in Anesthesia States: Surgery, Somatic Experiencing, and the Hidden Layers of Medical Trauma
A patient lies unconscious under anesthesia. The surgical team speaks quietly in the operating room while machines pulse rhythmically nearby. The body is immobilized. Conscious awareness appears absent. From the outside, the person seems entirely disconnected from experience.
Yet new neuroscience suggests something far more complicated may be occurring beneath the surface.
A recent study published in Nature found that the anesthetized human hippocampus continues processing meaningful information even during deep general anesthesia (Katlowitz et al., 2026). Researchers observed that the brain was not only responding to sounds, but differentiating speech patterns, tracking semantic meaning, distinguishing grammatical categories, and even predicting upcoming words in spoken language. Neural activity also demonstrated signs of learning and plasticity during the anesthetized state.
For many clinicians working within Somatic Experiencing (SE) and related body-based trauma therapies, these findings resonate deeply with long-standing clinical observations. SE has long proposed that trauma is not solely encoded through conscious narrative memory. Instead, traumatic experience may be carried through autonomic activation, procedural memory, neuroception, muscular tension, interoceptive signaling, and unresolved defensive responses. In this model, the body can continue processing experience even when the conscious mind cannot fully organize or remember what occurred.
Surgery may represent one of the clearest examples of this phenomenon.
The Body Under Surgery
From a physiological perspective, surgery places the organism into an extraordinary state of vulnerability. The body is penetrated, immobilized, restrained from action, and exposed to profound shifts in autonomic regulation. At the same time, anesthesia suppresses ordinary conscious awareness and voluntary behavioral response.
Traditionally, medicine has often conceptualized anesthesia as a kind of neurological “off switch.” If the patient is unconscious and later lacks explicit memory, the assumption has been that the experience itself was largely absent.
The emerging neuroscience complicates this assumption.
Katlowitz and colleagues (2026) recorded single-neuron activity from the hippocampi of patients undergoing epilepsy surgery while under propofol anesthesia. Their findings demonstrated ongoing high-level processing despite unconsciousness. Neural populations continued responding to auditory oddball signals, differentiated semantic categories of words, encoded parts of speech, and generated predictive processing related to upcoming language.
Importantly, the patients did not later report explicit memories of these experiences. Yet the nervous system continued processing information in sophisticated ways.
This distinction is central to trauma theory.
SE and related somatic models have repeatedly emphasized that the absence of conscious recall does not mean the absence of physiological encoding. Many trauma survivors experience bodily reactions, panic responses, chronic tension, or autonomic dysregulation linked to events they cannot fully narrate. The body often “remembers” in ways the narrative mind cannot easily access.
Within SE, trauma is understood less as the event itself and more as the unresolved physiological response to overwhelming experience. The nervous system mobilizes for defense but becomes unable to complete protective actions. Fight, flight, orienting, or protective withdrawal are interrupted or suppressed, leaving the organism trapped in persistent dysregulation.
Surgery creates precisely this kind of paradoxical state.
The organism is exposed to profound bodily threat while simultaneously prevented from action.
The Unfinished Defensive Response
Animals in the wild survive threat partly through completion of defensive responses. They orient, flee, fight, freeze, discharge activation, and eventually return toward regulation. SE proposes that trauma emerges when these processes become interrupted or incomplete.
Under anesthesia, the body may still register aspects of danger or physiological disruption while the individual remains incapable of behavioral completion or conscious orientation. The nervous system may continue monitoring signals of safety, uncertainty, or vulnerability even while conscious awareness is heavily altered.
This possibility aligns closely with Stephen Porges’ concept of neuroception, the nervous system’s automatic evaluation of safety and threat outside conscious awareness (Porges, 2011). Neuroception operates continuously beneath deliberate cognition, shaping autonomic state and defensive readiness.
The operating room is therefore not merely a technical medical environment. It is also a powerful neurophysiological environment.
Tone of voice, predictability, relational safety, bodily handling, sensory stimulation, and physiological regulation may all matter more than medicine has historically assumed.
The findings by Katlowitz et al. (2026) do not suggest that anesthetized patients are secretly awake in the ordinary sense. Rather, they suggest that meaningful information processing persists beneath conscious awareness. The hippocampus remained capable of integrating, categorizing, and anticipating sensory information even in an unconscious state.
For trauma clinicians, this is a familiar idea.
The nervous system often continues processing experience long after consciousness has narrowed or disengaged.
Medical Trauma Without Narrative Memory
Many clinicians encounter patients who develop symptoms after surgery that are difficult to fully explain through conventional medical recovery alone. Patients sometimes describe unexplained anxiety, heightened vigilance in medical settings, dissociation, panic symptoms, sleep disruption, chronic pain amplification, or diffuse feelings of bodily unsafety following procedures they barely remember.
Historically, these reactions may have been minimized because patients lacked explicit traumatic recollection. Yet trauma research increasingly demonstrates that implicit memory systems can shape emotional and physiological functioning independently of autobiographical narrative (van der Kolk, 2014).
The new findings may help explain why medical trauma can emerge even when conscious memory appears absent.
The body may still encode:
helplessness,
loss of agency,
physiological overwhelm,
invasive bodily experience,
autonomic activation,
and relational cues associated with vulnerability.
For SE practitioners, surgery may therefore require greater recognition as a potentially dysregulating experience for some nervous systems, particularly among individuals with prior trauma histories, attachment disruptions, chronic illness, or preexisting autonomic instability.
Toward Trauma-Informed Surgical Care
These findings invite a broader conversation about trauma-informed medicine.
If the nervous system continues processing meaningful information under anesthesia, then perioperative care may need to include more than technical physiological management alone. It may also require attention to relational and autonomic safety.
Potential implications include:
preparing patients with grounding and orienting practices before surgery,
supporting predictability and agency whenever possible,
reducing frightening sensory exposure,
using calming and respectful communication throughout procedures,
supporting autonomic settling during recovery,
and recognizing post-surgical dysregulation as a legitimate clinical phenomenon.
SE-informed interventions may become particularly relevant in postoperative care, ICU recovery, pediatric surgery, and chronic pain treatment. Helping patients restore orienting responses, complete residual defensive activation, and rebuild a felt sense of bodily safety may reduce lingering dysregulation after invasive medical experiences.
The deeper significance of this research extends beyond anesthesia itself. It contributes to a growing recognition within neuroscience that conscious awareness represents only one layer of human processing. Beneath deliberate cognition, the nervous system remains active, predictive, relational, and adaptive.
The unconscious brain is not inactive.
It listens. It learns. It anticipates.
And sometimes, the body continues carrying experiences that the conscious mind cannot fully remember.
